E. "Reasonable restrictions on a solar energy system" means those restrictions that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance, or that allow for an alternative system of comparable cost, efficiency, and energy conservation benefits. F. "Restrictions that do not significantly increase the cost of the system or significantly decrease its efficiency of specified performance" means: 1. For water heater systems or solar swimming pool heating systems: an increase in the cost of the system, as originally proposed, exceeding ten percent (10%) of the cost of the system, but in no case more than one thousand dollars ($1,000), or a decrease in the efficiency of the solar energy system, as originally proposed, exceeding ten percent (10%). 2. For photovoltaic systems: an amount not to exceed one thousand dollars ($1,000) over the system cost as originally proposed, or a decrease in the efficiency of the solar energy system, as originally proposed, exceeding ten percent (10%). G. "Specific, adverse impact" means a significant, quantifiable, direct, and unavoidable impact, based on objective, identified, and written public health or safety standards, policies, or conditions, as they existed on the date the application was deemed complete. 20.70.030 Applicability A. This chapter applies to the permitting of all small residential rooftop solar energy systems and electric vehicle charging stations in the City. B. Small residential rooftop solar energy systems and electric vehicle charging stations legally established or permitted prior to the effective date of the ordinance codified in this chapter are not subject to the requirements of this chapter unless physical modifications or alterations are undertaken that materially change the size, type, or components of a small rooftop energy system in such a way as to require new permitting. Routine operation and maintenance shall not require a permit. 20.70.040 Solar Energy System Requirements A. All solar energy systems shall meet applicable health and safety standards and requirements imposed by the state and the City. B. Solar energy systems for heating water in single-family residences and for heating water in commercial or swimming pool applications shall be certified by an accredited listing agency as defined by the California Plumbing and Mechanical Codes. C. Solar energy systems for producing electricity shall meet all applicable safety and performance standards established by the California Electrical Code, the Institute of Electrical and Electronics Engineers, and accredited testing laboratories such as Underwriters Laboratories, and where applicable, rules of the Public Utilities Commission regarding safety and reliability. 20.70.050 Electric Vehicle Charging Station Requirements A. Prior to submitting an application for processing, the applicant shall verify that the installation of an electric vehicle charging station will not have specific, adverse impact to public health and safety and building occupants. Verification by the applicant includes but is not limited to: electrical system capacity and loads; electrical system wiring, bonding and overcurrent protection; building infrastructure affected by charging station equipment and associated conduits; areas of charging station equipment and vehicle parking. B. Electric vehicle charging station equipment shall meet the requirements of the California Electrical Code, the Society of Automotive Engineers, the National Electrical Manufacturers Association, and accredited testing laboratories such as Underwriters Laboratories, and rules of the Public Utilities Commission or a Municipal Electric Utility Company regarding safety and reliability.
